78098724 ÷ 20 
We want to figure out the number of times 78098724 can be divided by 20.

Let's proceed to step 1:
20 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

Let's proceed to step 2:
If we divide 78 by 20, we get 3 and a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 60 from 78 to get 18.
Grab the next digit (0) from the dividend, add it to 18, then carry on: 180 / 20

Going ahead to step 3:
20 goes into 180 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 39.0
The remainder is 0 after subtracting 180 from 180.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 20

Going ahead to step 4:
9 divided by 20 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 390.0
If we take 0 away from 9, we end up with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 20

Moving on to step 5:
20 can be fit into 98 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 3904.0
Subtract 80 from 98 to get 18.
Bring next digit (7) of the dividend behind the 18 and repeat the process: 187 / 20

On to step 6:
20 can be fit into 187 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 39049.0
If we subtract 180 from 187, we get 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

Advancing to step 7:
72 divided by 20 is 3 with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 390493.0
Deduct 60 from 72 and we're left with 12.
Include the next digit (4) from the dividend after 12, then repeat: 124 / 20

Step 8:
When dividing 124 by 20, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 3904936.0
If we subtract 120 from 124, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 9:
40 divided by 20 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 3904936.2
If we take 40 away from 40, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 3904936.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 3904936.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 3904936.2 and a remainder of 0.0.
